Question 1
Question 1 refers to the following photograph and chart. Hurricanes such as the one pictured above gather strength as they pass over warm water. According to the chart above, over which of the following bodies of water would a hurricane gather the most strength?
Correct Answer:
Gulf of Mexico
Explanation:
Correct answer: Gulf of Mexico
Question 2
Blood is made up of two main elements: (1) plasma, which is largely water and proteins, and (2) the solid components of blood—red blood cells, white cells, and platelets (important for forming clots). If a patient has lost a lot of blood, he or she may receive a transfusion of “whole blood,” which includes red blood cells and plasma. However, sometimes the patient needs only an increase in the volume of liquid in the bloodstream, in which case plasma alone may be substituted. A person must be tested for blood type before receiving certain kinds of transfusions because of differences in the ways that red blood cells react to one another. Under what conditions would such testing be necessary?
Correct Answer:
for whole blood transfusions only
Explanation:
Correct answer: for whole blood transfusions only
Question 3
Questions 3 through 5 are based on the following information. Coal is formed from the material of plants and other organisms that lived on land and whose remains were covered by mud, which later became rock. Coal is classified by carbon content. Peat = The remains of plants and organisms that, because they were covered in bogs, were prevented by a lack of oxygen from completely decaying. Still a porous, soft brown mass, peat has a carbon content of 52%–60%. Lignite = In time, peat turns into lignite, a soft coal-like substance that is 60%–65% carbon. Subbituminous coal = With more time, heat, and pressure, lignite changes into subbituminous coal, which is about 65%–75% carbon. Bituminous coal = After even more heat and pressure, subbituminous coal turns into bituminous coal with a carbon level of 75%–85%. Anthracite = This is bituminous coal subjected to another million years of heat and pressure. Anthracite has a carbon level of 85%–95% and will burn only at extremely high temperatures. A researcher analyzes a piece of coal and finds that it is unusually dense and burns only when subjected to very intense heat. What is the lowest percentage of carbon that this coal is likely to contain? Enter the _____ %.
Correct Answer:
85%
Explanation:
Those properties identify anthracite, whose stated carbon range begins at 85%. Correct answer: 85%

Exam overview

About this Exam

The GED (General Educational Development) Science test is one of four subject exams designed to measure a person's knowledge and skills in key academic areas.

Successfully passing this exam demonstrates that an individual has the high school-level science competencies required by employers and colleges.

The test is intended for adult learners who did not complete their formal high school education and are seeking to earn an equivalency credential.

This practice exam is a crucial tool, simulating the format, timing, and types of questions found on the real test, allowing candidates to build confidence, manage their time effectively, and pinpoint areas that need more review.

Additional Information

What the Course Entails and Exam Details

This practice exam is structured around the core topics and skills outlined in the official GED Science assessment.

It focuses on three main content areas:

  1. Life Science (approx. 40%): Topics include cell biology, ecosystems, human body systems, genetics, and molecular biology. Students must understand essential processes like photosynthesis and cellular respiration.

  2. Physical Science (approx. 40%): This section covers fundamental chemistry and physics principles, such as atoms and chemical reactions, forces, motion, energy, and waves.

  3. Earth and Space Science (approx. 20%): Key areas include the solar system, geological processes, weather, and climate systems.

In addition to subject knowledge, the exam heavily tests mathematical and reasoning skills within scientific contexts, such as interpreting data from charts and graphs, understanding experiments, and evaluating scientific evidence.


What to Expect in the Final Exam

The actual GED Science test is a computer-based examination that lasts approximately 90 minutes.

It consists of approximately 34-40 questions, with around 35 being common in current versions, all designed to assess scientific reasoning.

You will encounter various question formats, including:

  • Multiple Choice: Selecting the best answer from several options.

  • Drag-and-Drop: Moving elements to complete a diagram or match definitions.

  • Hot Spot: Clicking on a specific area of an image to answer.

  • Fill-in-the-Blank: Typing a word, number, or short answer.

  • Short Answer: Writing a brief response based on information provided.

Some questions will be based on passages of scientific text, diagrams, tables, and graphic data.

You can skip questions and mark them for review to return later during the 90-minute time frame.

A non-programmable, standard calculator is embedded in the digital test interface, often a TI-30XS, and you can use digital or physical scratch paper.

A passing score is typically set at 145 out of 200 for high school equivalency.


How to Study and Exam Centers

Effective preparation is key to succeeding on the GED Science test.

Develop a consistent study routine.

Use official GED study guides, reputable online courses, and scientific textbooks to cover the core content areas of life, physical, and earth science.

Focus on interpreting graphs, charts, and diagrams, as many questions rely on graphical information.

Take timed practice tests frequently to build speed and accuracy.

Analyze your mistakes to understand where your knowledge gaps lie.

Create flashcards for essential vocabulary and formulas.

Consider forming or joining a study group for support and shared learning.

As the test date approaches, ensure you are well-rested and prepared.

To take the actual GED exam, including the science subject test, you must first register and schedule your tests through the official website, GED.com.

You can opt for in-person testing at an official GED Testing Center, which are often located in community colleges, adult education centers, or professional testing facilities like Pearson VUE centers.

Online proctored testing is also an option for eligible candidates who meet certain technical requirements and follow strict proctoring protocols.

Check local guidelines for specific physical testing locations near you.
